Haha, there isn't a thing that makes you 'really smart'.
However, you can grow and improve your knowledge.
The more challenging material you expose yourself to, while putting in the effort to solve them, there's no doubt you'll definitely improve!
+ you can try exercising your brain every now and then by playing trivia games or reading books- do whatever interests you and helps you learn!
I believe the answer would be 36.
Hope this helped you. ;}
Answer:
73.5
Step-by-step explanation:
circumference = 2πr , where r = radius
given radius = 11.7 so r = 11.7
C = 2πr
==> plug in r = 11.7
C = 2π(11.7)
==> multiply 2 and 11.7
C = 23.4π
==> multipl 23.4 and π
C = 73.5 ( rounded to the nearest tenth )
No, since 0 doesn't belong to the domain.
